1. INTRODUCTION

This manual (describes the handling. use and operating principle of type

SZE21

Multifunction Motor Protection Relay.

The

S2E21

is a motor protection relay and monitor incorporating protective

features for 3-phase induction motor and motor monitor units having such

functions as motor temperature and operation trends.

S2E21

has the following features.

(1)

(2)

(3)

(4)

Temperature-based protection adopted for overload protection unit:

The ove:rIoad protection function employs a temperature-based protection

method

.that

calculates the motor temperature rise from the motor’s heat

characteristic and motor current and provides optimum protection for various

kinds of motors.

Large LCD screen:

The large easy-to-read LCD screen makes the

S2E21

highly operable.

All protective functions necessary for motor circuits integrated:

The

S2E21

incorporates all protective functions necessary for the motor

circuits, including overload. short-circuit, overcurrent, unbalance,

undercurrent, ground overcurrent, directional ground, abnormal starting and

starting failure, and repeated starting.

A variety of motor management information available:

The

S2E2l

offers a variety of information useful for motor management and

maintenance, including motor temperature, number of ~starts made. operation

time, current trend at fault and operation history.

Communication and memory card equipped as standard:

The

S2R21

cOnes

standard with a communication port

(RS485)

and a memory

card, facilitating the setting, setting charges and motor monitoring.

(6) Monitor

(to

be purchased separately) makes the maintenance work very easy.
